[OpenJDK 2D-Dev] 2 small xrender fixes

[Clemens Eisserer]

Hi,

I would like to get two (very small) changes to the xrender-pipeline in:

1. http://93.83.133.214/ignore-whitespace-width.zip deals with the
fact that the closed-source
font rasterizer seems to generate width=65535 for whitespaces, which
resuts in software fallbacks.
Granted with height=0 rendering should be completly omited by the X
server, but as it seems it isnt.

2. http://93.83.133.214/synchronize-native-cairo-ops.zip
synchronize-native-cairo-ops synchronizes access to Jules's native
functions.
There seems to be a race somewhere in cairo and I wasn't able to hunt
it down, so synchronizing is the best I can do for now.

Do I need to create two different bug-reports? Is OpenJDK Bugzilla enough?
